The Hermit's Cave was a radio horror anthology series, syndicated by WJR Detroit in the mid-1930s, sponsored by Olga Coal after the first two years. As the wind howled, the ancient Hermit narrated his horror fantasies from his cave. The cackling character of the Hermit was played by John Kent, Charles Penman, Toby Grimmer, and Klock Ryder.

William Conrad produced when the show moved to KMPC Los Angeles with Mel Johnson as the Hermit (1940-42), followed by John Dehner (1942-44).
